Computational Studies And Finite Element Analysis For The Traditional Column And Tie Timber Construction

China's wood structure in the construction of the world is unique,China's ancient architecture of the wood structure are mainly lifting beam,wear bucket and well dry three forms.China's contemporary scholars on the beam-type research mostly on the wear-type structure is relatively small,its derivative type and the difference between the beam and column is not clear enough,especially for the structure of the bucket structure of the various components of the calculation and seismic performance of the research is very few,there is no molding method and model,while many of our ancient and ancient architecture in the human and natural damage under the effect of serious,in this case to the dwelling-based structure of the safety of the bucket can not guarantee,At the same time on the bucket structure of the ancient building reinforcement repair blocked.In this paper,the classification of the bucket structure and the type of derivative are given by summarizing the research of the existing bucket structure.Through the destruction of the bucket structure in the past earthquake,the main types of damage are discussed and sorted out.This paper analyzes the load transfer process of the bucket structure,and establishes a calculation method for the calculation of the structure of the bucket structure and the purlins and the wear of Fang and other components.Bucket structure of the roof system,respectively,according to the one-way plate elastic theory and two-way plate plasticity theory to calculate,and gives purlin rafters design basis.Finally,the article uses the finite element software ANSYS to compare the analysis of the bucket structure in the enclosure structure and no envelope of the two cases of static analysis know that under the action of the self-weight under the envelope structure of the displacement are less than no envelope The bucket structure.Through the seismic response analysis,it is known that the basic cycle of the dwelling structure of the enclosed structure is about 0.3371 s.The basic cycle of the torsion is about 0.3305 s,the longitudinal and basic cycles of the structure are basically the same.Under the earthquake,The structure may appear in the form of adverse torsional coupling vibration form,compared to the no envelope structure,the envelope structure due to the strengthening of lateral capacity,the seismic performance to be better.At the same time,according to the seismic displacement time-history curve of each node,it is known that the bucket structure has a good energy dissipation mechanism under the earthquake and medium shock,and the ideal energy dissipation mechanism under the action of the earthquake is not so obvious.
